Thallium Bromide (TlBr)

Thallium Bromide (TlBr) is a promising room temperature gamma radiation semiconductor detector material due to its high Z component and high density. It has higher photoelectric and total attenuation coefficients than other semiconductor detectors for gamma-rays with energies greater than 20 keV. For example, the attenuation length of 662 keV photons incident on TlBr is 1.4 cm, significantly shorter than that for CZT (2.3 cm).
